sims problem

I keep getting "failed to find and directX 9.0c...." when I try to play it...

my sound doesn't work either, I believe its for the same reason. Anyway..

Someone built my computer for me and the sims worked fine but then I had a virus and I had to erase everything and now it won't play. What I know my pc has is:

K7 Triton series agp8X/dual channel DDR motherboard
Windows Xp
I think the processor is: AMD Athlon
1.24 GHz, 1.00GB of RAM
Network Adapters: 1394 Net Adapter and
Realtek RTL8139 Family PCI Fast Ethernet NIC

sound video and game controllers:
NVIDIA nForce Audio Codec Interface
legacy video capture devices
legacy audio drivers
standard game port
Creative SB Live! Value
Creative SBLive! Gameport

help?

Did you get rid of the virus?

Do this:
Go to www.google.com and search DirectX 9.0c and download the driver and reinstall the Sims

Hope I helped

Thanks but that didn't work.

I did get rid of the virus.
